Title: Improvements in methods of treating industrial liquids with metered quantities of a solid product
IPC: C02F1/68
Filed: 1957-09-12
Abstract: 846,590. Mixing solids with liquids in flow. PROSIMACFI. Sept. 12, 1957 [Sept. 17, 1956], No. 28803/57. Class 86 [Also in Group XVIII] In an apparatus for treating industrial liquid (e.g. boiler feed water flowing in a pipe 1) by distributing therein a metered quantity of solid treating product (water softener briquettes B) the liquid to be treated, or a part thereof, flows down the inclined plane bottom 9 of a container 4, of the solid, and in contact with the solid. Saturation of the liquid by the solid is thereby avoided whilst correct proportioning of the solid dissolved and the liquid flowing over the bottom 9, is maintained. As shown, boiler feed water is supplied intermittently through a pipe 1 to a locomotive boiler 2, when steam injector 12, supplied with steam through a pipe 13, is actuated. A branch pipe 3 is connected through a regulator cock 14 to the upper end of the inclined container 4. The water passes into an upper end compartment 6, through perforated partition 5 of a central compartment for the briquettes B, to a lower end compartment 7 connected by a pipe 8 to the pipe 1 at the input side to the injector 12. Excess water is bypassed from the cock 14, by a pipe 16, to the pipe 8. The container 4, in some applications, may discharge directly into the point of utilization of the treated liquid and in the apparatus shown may be divided into two separate units by partitions as described with reference to Fig. 3 (not shown).

Abstract: 691,585. Humidifying air. FELDERMANN, W. Dec. 10, 1951, No. 28894/51. Class 55(ii) In an air-humidifying apparatus, the motor 7, and the water-atomizing means driven thereby, project through and are carried by a ring 21 which carries also a water pan 27 and an outer casing 32.

Title: Improvements in or relating to the manufacture of woollen textile fabrics
IPC: D03D15/00
Filed: 1945-10-31
Abstract: Lightweight woollen fabrics are produced by treatment of a fabric comprising yarns containing both wool fibres and fibres of a cellulose ester or ether with a solvent for the cellulose derivative. The proportion of wool in the yarn should be less than 60 per cent and may be from 15-40 per cent.  Preferably the yarn should be composed of staple fibres and may be either singles or doubles.  The fabric should be closely woven (at least 40 picks to the inch), the actual weave being immaterial.  Knitted fabrics may also be treated. The fabric should contain at least 3,000 yards of yarn per square yard, and less than 2 ounces of wool. The cellulose derivative may be cellulose acetate and the solvent acetone or it may be any other cellulose ester or ether with any appropriate solvent.  In an example a plain woven fabric of yarns consisting of 30 per cent wool and 70 per cent cellulose acetate staple fibre, the warp having 58 picks and the weft 60 picks to the inch is extracted with acetone, giving a fabric of weight about 1.5 ounces to the yard.  The Provisional Specification also refers to the treatment of fabrics formed from yarns comprising wool fibres and fibres of filament-forming substances other than cellulose esters or ethers, the said substance being soluble in liquids having no deleterious action on the wool fibres.

In a vehicle direction-indicator of the flashing light type, a first three-position switch 5, for controlling the front lamps 7, is in series with a flasher unit 9, there being a relay coil 10 connected in series (Fig. 2, not shown) or parallel with the flasher; a second three-position switch 4 (ganged to the first) for operating the rear lights 6 is in series with the relay contacts 11 while a pilot lamp 14 connected across the contacts 11 operates in antiphase with the rear lights 6 and in addition a resistor 12, with a shorting switch 13, is connected in series with the second switch 4 so as to reduce the illumination of the rear indicator lamps when the driving lights are in use. If a turn is to be made, ganged switches 5 and 4 are operated, and lights 6 are illuminated since relay 10 is energized. After a delay thermo-electric flasher 9 shorts the relay, the front lights 7 are illuminated and a pilot light 14 is lit but due to its high resistance, lights 6 remain out. The cycle then repeats. If a rear light 6 should fail, the pilot light 14 will not operate and if a front lamp 7 fails, the pilot will burn continuously. Switch 13 is ganged to a driving light control switch and upon operating the latter, resistor 12 is introduced into the rear light circuit. A similar circuit but using two sets of relay contacts and two pilot lights is depicted in Fig. 3 (not shown).

Abstract: 282,954. Greenwood, C. H. Nov. 23, 1926. Turning-gear.-In a starter for motor-vehicle engines of the kind in which a starting motor drives through the gear box, the starting motor drives a sliding pinion f adapted to engage a gear wheel i keyed to the driving shaft within the gear box. As shown, the pinion f slides on a shaft c driven through chain gearing from an electric motor mounted on the side of the gear box b, and the wheel i is immediately in front of, and may be integral with, the constant-mesh pinion k of the gear box. The pinion f may be moved by means of a fork g on the selector rod h which operates the reverse, the gear lever being moved into a special compartment of the gate to effect movement of the pinion. In operation, the main engine clutch is disengaged, the gear lever is moved to the starting position, the electric motor is switched on and allowed to gain momentum, and the clutch is engaged to enable the engine to be started. The clutch is then disengaged, the switch released, and the gear lever returned to neutral.

The bi-stable counter portion includes a pair of vertical NPN transistors 12<SP>1</SP>, 14<SP>1</SP> and two PNP multi-collector lateral transistors 16<SP>1</SP>, 18<SP>1</SP>, the buffer stage a vertical NPN transistor 70<SP>1</SP> and PNP lateral transistor 72<SP>1</SP> and the converter an NPN vertical transistor 92<SP>1</SP>. The epitaxial layer forms the collector of each NPN transistor and the base of each PNP transistor of every stage. The base zone of each NPN transistor forms also a collector of one or more of the PNP transistors, and where direct interconnection of the base of a PNP transistor and the collector of an NPN transistor is required a buried N+ layer is disposed under the connecting path, as shown by the areas enclosed by dashed lines 130 in Fig. 3. Resistors 36<SP>1</SP>, 38<SP>1</SP>, 80 are defined by narrow extensions of zones of the transistors.
